snowflake.snowpark.functions.sha2_binary¶

snowflake.snowpark.functions.sha2_binary(msg: Union[snowflake.snowpark.column.Column, str], digest_size: Union[snowflake.snowpark.column.Column, str] = None) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.44.0/src/snowflake/snowpark/_functions/scalar_functions.py#L4182-L4209)¶

Returns a binary SHA-2 hash of the input message. The digest size determines the hash algorithm used.

Parameters:

• msg (ColumnOrName) – The input message to hash.

• digest_size (ColumnOrName, optional) – The digest size in bits. Valid values are 224, 256, 384, and 512. Defaults to 256 if not specified.

Returns:

A binary representation of the SHA-2 hash.

Return type:

Column
